Maven Build Failing Following Upgrade to 5.0.0

You can solve the issue without modifying your local JDK by including the maven-soapui-plugin like this:

<properties>
    <version.soapui>5.1.3</version.soapui>
</properties>
<build>
    <plugin>
        <groupId>com.smartbear.soapui</groupId>
        <artifactId>soapui-maven-plugin</artifactId>
        <version>${version.soapui}</version>
        <dependencies>
            <dependency>
                <groupId>com.smartbear.soapui</groupId>
                <artifactId>soapui</artifactId>
                <version>${version.soapui}</version>
                <exclusions>
                    <exclusion>
                        <groupId>javafx</groupId>
                        <artifactId>jfxrt</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
        </dependencies>
        <!-- ... -->
    </plugin>
</build>

That should work if you don't use features that need the JavaFX runtime (OAuth2?!).
